I'm not disupting that he can write well, nor that he has many quality works. But it seems when someone says "in the tradition of Martin" it means "like ASoIaF." His works are all so very different, so what exactly is the tradition? It's not like saying, "In the tradition of David and Leigh Eddings," where they only write one thing, one way, and that's what you can expect. Honestly, I'm not sure that many people know he wrote all those other books. They're not shelved in fantasy for the most part (with the exception of Wild Cards).
